RADIATOR;

Application filed June 10,

The invention relates to radiators of that kind and'type which arecommonly used in connection with a central heating plant to heat roomsin dwellings, oflice buildings etc. Such radiators are beingused inconnection with steam heating plants and hot. water plants, but ingeneral the appearance and construction of these radiators heretofore inuse are practically the same. Each radiator consists usually of aplurality of heating units which are put together by means of flangesfitting onto each other. Between the adjacent units spaces are left sothat air may get in touch with practically, all the outer surface of theunits forming the radiator whereby a circulation of air may be createdin the room to be heated. The radiators mentioned are usually set asnear as possible to a wall but owing to construction of the radiator itmust be set 3, 4t and 5 inches away from the wall and since the depth ofa radiator is about 9 inches, each radiator takes up an appreaciablepart of floor space when the modern tendency to build small flats andapartments is taken in consideration of the radiators. This is onedisadvantage and until now, another disadvantage, is that it ispractically impossible to clean the space underneath and about theradiator, so that dust and other dirt accumulating underneath and aboutthe radiator will be carried upward with the current of air set up bythe radiator during the heating season and said dust and dirt will thendiscolor and smudge the walls in the ne-igh borhood of the radiator.

The objects of the present invention therefore are to provide a radiatorwhich will offer at. least as much surface of radiation asthe radiatorused heretofore and which at the same time will not take up so. muchfloor space. a 1

A further object of the invention is to provide a radiator which can bebuilt right into the wall thereby making it possibleto heat two roomswithone radiator. This was not possible with the radiators heretofore-inuse on account of the spaces between adjacent heating units of theradiator. If an old radiator would be built into a wall an uncoveredopening would exist connecting the two rooms. The radiator according tothe present invention has a continuous mantle or wall so that it can bebuilt into a wall separating two rooms without per- 1927. 'Serial No.197,857.

ther object of the invention is to provide a radiator the longitudinaland side walls whereof are made of sheet metal and the tops and bottomswhereof are cast into said walls.

()ther objects not specifically mentioned will be easily understood andascertained from the following descriptionv on hand of the accompanyingdrawings forming a part thereof. It is however to be understood that theinvention is not to be limited or restricted to the exact constructiondescribed in the specification and shown on the drawings but that suchchanges and alterations may be madeas fall within the scope of theclaims appended hereto.

In the drawings Fig. 1 is a vertical longitudinal section through theradiator according to the invention, said section being taken 011 linel1 of Fig. 2.

Fig. 2 is a section taken on line 2-2 of Fig. 1. j j

Fig. 3 is a side view of radiator according to Figures 1 and 2. V

Fig. l is a front view of a slightly modified form of the radiatoraccording to the invention.

Fig. 5 is a section on line 55 of Fig. 4.

Fig. 6 is a section on line 66of Figure 7 and Fig. 7 is a partial frontview of another modified form of the invention.

Fig. 8 is a section on line 8-8 of Fig. 9 and Fig. 9 is a broken view ofstill another modified form of the invention.

lccording to the Figures 1, 2 and 3 the radiator has an outer wall 11which is made from one continuous piece of sheet metal. The mantle has"two series of pipe shaped portions 12. The pipes of each series arearranged in regular intervals and extend vertically. j j

The two series are located at equal distances from the vertical centerplane of the radiator. I The pipe like portions are not entirely closedOn the outermost portion of the periphery a slot is provided extendingover the whole height of'the -wall, so that airmay enter the-pipe likeportions and get into contact with they inner surface of said portions.Adjacent pipe like portions are then connected by curved portions 13.The are of these pieces 13 is preferably taken in such a manner, thatthe center of said arcs 1s located on the vertical-center plane of theradiator. Adjacent the different pipe like portions 12 real pipes 14 areprovided and are arranged so that their axes will substantially belocated in the vertical center plane of the radiator. I These pipes areheld by the top 15 and the bottom 16 of the radiator which are cast intothe mantle 11 while the pipes 14 are held in position in anysuitablemanner. In order to increase" the surface of radiation of the radiatorstill more, the metalforming the pipe like portions 12 i of the radiatormay be bent toward the center I over the whole height of the radiator.In

case of the radiator being used in connection with a steam heating planta pipe 20 leading from the boiler is connected by a three way valve 21tothe feed pipes 22 and 23 respectively. The stiffener plate 19 which,as stated above, extends over the whole height of the radiator dividessaid radiator in two parts or portions. Said parts may be of equal size,

or as indicated in Fi 1 one art ma be greater or bigger than the otherof said parts and the pipe in 23 in the other part. The feed pipeextends into the neighborhood of the top of the radiator. It is evidentthat by means of the three way valve 21 both parts of the radiator maybe heated, or either one of said parts or none of said parts justasdesired. In order to let the condensate water, which would collect inthe radiator, return to the boiler, holes 24 are provided in the feedpipes 22 and 23 adjacent the bottom 16 of the radiator and the legs 25may be high enough to facilitate the cleaning underneath the radiatoror, in case said radiator is to be set into a wall, to facilitate thebuilding in of the radiator into, said wall.

The radiatoras described in connection with Figures 1, 2 and 3 has amantle which, as

stated above, consists of one piece of sheet metal, so-that thewholeradiator really is one unit. It may however be desired to build upa radiator out of aplurality of units; This is provided for in themodification shown in Figures 4 and 5. In this case the wholeconstruction and formation ofthe radiator is exactly the same asdescribed above and shown in Figures 1, 2 and 3 with one exception:Instead of having closed end walls, as indicated at 26 in Fig. 2, theradiator is provided with an end wall formed with side flanges 27 and 28respectively and having a slot like opening 29 so that two such unitsmay be placed alongside of each other and may then be connected in anysuitable man ner. It is understood that theend unit of a radiatorconsisting of a plurality of units would be shaped on its outer end asindicated at 26 in Figure 2.

In Figures 6 and 7 and Figures 8 and 9 some other modifications of theradiator are shown which have as their object to provide aradiator whichhas not quite as big a radiation surface as shown and describedheretofore. In addition to that the radiator as shown in Figures 6, 7, 8and 9 may be set right up against a wall without injuring the wallthrough the heat radiated thereby. In Figure 6 only one series of pipeshaped portions 30 is indicated which in itself is exactly of the sameconstruction as the pipe like portions 12 described heretofore. The mainchannel 31 of the radiator carries on the side opposite the pipe likeportions channel ribs 32, and arranged oppositely of these channel ribs,other channels 33 which'are arranged in the wall of the pipe likeportion 31. Strengthening plates 34 are then set into these oppositechannel ribs whereby the mantle of the radiator is stiffened asindicated in Figure 6.

The radiator according to Figures 6 and-7 may be provided with endflanges 35 or it may be provided with closed wall as described above.

The radiator according to Figures 8 and 9 is practically the same astheradiator in Figures 6 and 7 with the exception that at one side aseries of pipe like portions30 are provided and on the other side of thevertical centerplane of the radiator a series of portions 36 which arehalfround and two adjacent halfround portions 36 are then connected witha flat channel piece 37. This gives a somewhat greater radiation surfacethan the radiator according to Figures 6 and 7 but somewhat less thenthe radiator according to Figures 1, 2,3, 4, and 5.

In Figure 9 is indicated how this radiator according to the inventionmay be used in connection with a hot water heating plant. In this case afeed pipe 38 leads from the boiler to the radiator and a drain pipe 39leads the water back to the boiler.- This drain pipe 39 is connected bymeans of'a 3 inch valve 40 to the drain pipes 41 and 42 respectivelyleading into the bottom portion of the radiator. This radiator may alsobe divided into the two heating units by means of a dividing plate 42.In this case however the dividing wall 43 must be provided with someopenings adjacent the top thereof to permit the hot Water enteringthrough the feed pipe 38 into the left side of the radiator to flow intothe right hand side thereof.

The mantle of the radiator is to be made as stated above from, sheetmetal and preferably 7 metal which will not be attacked by rust or thelike caused by hot water and steam. In order to make it possible to usecheaper material such as sheet steel it would be necessary to line themantle with a metal which will not corrode under the influence of wateror steam for instance copper or copper alloys.

The above description and the drawings show very plainly that thepressure of the steam or the water on the walls of the differentportions of the sheet metal mantle will act in such a manner that thepressure will for instance tend to flatten the pipe shaped portions. Itis a well known fact that a pipe can withstand quite a high pressurebefore it gives way and for that reason the construction of themantleaccording to the present invention will be strong enough even ifit is only made from sheet metal.

\Vhat we claim as new and desire to secure by Letters Patent is:

1. In a radiator of the class described a sheet metal wall formed into aseries of spaced apart pipe shaped portions, each portion having aslotlike opening on the out-side part of its periphery, said opening-extending over the whole height of the wall and each edge of such anopening being connected with the adjacent edge of the slot in the nextpipe shaped portion by means of a portion of the sheet metal wall, aplurality of channel shaped ribs formed by the metal of the mantle ofthe pipe shaped portions and extending inwardly and radially of saidportions, a cast metal top, and a cast metal bottom, said top and bottombeing cast into the sheet metal wall thereby forming an integral unit.

2. In a radiator of the class described a sheet metal wall formed into aseries of spaced apart pipe shaped portions, each portion having aslotlike opening on the outside part of its periphery, said openingextending over the whole height of the wall and each edge of suchopening being connected with the adplate extending crosswise of theradiator and arranged in said corresponding ribs, a cast metal top and acast metal bottom, said top and bottom being cast into said wall therebyforming an integral heating unit.

3. In a radiator of the class described a mantle consisting of acontinuous sheet metal wall, a plurality of pipe shaped portions formedby the metal of said wall, a slotlike opening in the outside part of theperiphery of each pipe shaped portion and extending over the wholeheight of the wall, each edge of such opening being connected by a partof the sheet metal wall with the adjacent edge of the slot in the nextpipe shaped portion, a plurality of channel shaped ribs formed by I themetal of the continuous wall, the channels opening toward the inside ofthe radiator and some of the ribs of the front portion of the wallcorresponding with some of the ribs of the rear portion of said wall,stiffener plates arranged in the corresponding pairs of ribs, one ofsaid plates extending over the whole height of the wall, a cast metaltop, and a cast metal bottom, said top and bottom beingcast into theWall of the radiator thereby forming an integral heating unit.

In witness whereof we affix our signatures.
